Spamassassin: How do you "report email as Spam"

Hello and thanks,
I am trying to support a customer that uses Bluehost for their web hosting and e-mail.
They have been geting spam so I turned on Spamassassin
I access their e-mail accounts thru Horde

I have enabled Spamassassin; it is working; ie for e-mail accounts that are getting Spam, it created a Spam box and is moving most of the spam into this box...but,

It misses some, I want to flag those as spam ("report as Spam") so, going forward, they will automatically get moved to the Spam folder..

Also, I want to flag any valid e-mails that have been moved to the Spam box so they stop going there.

I cannot find how this is done, certainly it is an option?
I do see how to 'Move' or 'Copy' the e-mails from one folder to another...is this all I have to do then it will remember going forward?

I have searched the web and all I find is posting that talk about writing script...

Fine tuning Spamassassin and filters

Getting info on how to do this is next to impossible. I did a lot of playing with the settings to get a good rejection rate.

I made the mistake of posting my email in a "mailto:" on my website so I had plenty of spam to experiment with. Currently only a couple slip through each day. The following links take you to web sites that generate code that you use for your email that will obscure your email to spam bots.

You can customize Spamassassin (SA) from Bluehost's interface but I just took the users_prefs file and edit it directly then upload it. I looked at a lot of headers to see what SA was checking. I then tweeked the scores. I list my file at the end of this post.

There were still spam getting by SA so I wrote a few filters to deal with them.
FILTERS
1) From line doesn't end with com, net, gov, org or edu then send to spam
2) Crylic seems to sometimes louse up SA and the first filter so I wrote a regular expression that deletes the email if any of these letters are in the subject. The following is the reg exp.
à|á|â|ã|ä|å|æ|ç|è|é|ê|ë|ì|í|î|ï|ð|ñ|ò|ó|ô|õ|ö|÷|ø| ù|ú|û|ü|ý|þ|ÿ

Make sure all spam is sent to the spam box so you can check for false positives. When you are happy with the results, you can then have all spam get deleted. My SA file makes for a very restrictive filter. You will probably need to whitelist some address.

You can also write scripts for SA and train the baysian filter but I didn't want to take the time to figure out how to do this. If you create other filters with reg exp, you'll find some quirks but there is always a way to work around the issue.
